Position jumping / heading problem

If that is the case (powering off everything) then I think my next port of call would be power cycling individual components. Probably starting with the F9P, and maybe leaving it off off a minute or two.

Or do you mean you are just restarting the tablet, or even just restarting AOG?

No I left tablet on and AOG running. Just steerbox and aio off. Also tried reset IMU while problems occured, that didnā€™t help. Now I have to find a way to power off F9P without powering off the bnoā€¦ on the same pcb.

Of course I also tried to leave all components on and restart tablet and AOG. Thad didnā€™t help.

Random thought. Do you have a shielded cable on the WAS? With the drain setup properly (only attached at one end.

shielded cable, not drained I thinkā€¦ Never thought about this because the steering chart looks perfect. I will check this tomorrow and connect one end to chassis.
